Exist.
Why have I been able to see differences related to tuning and the stage if I give it burn in?
I notice the sound more mature and the soundstage looser and I would say expansive.
I had understood that since they are balanced armor there should be no changes with the burn in.
I clarify. I do NOT burn in my ears. I test the iems as it arrives and then I run it without listening for x hours.
Why?
